Asus Core i3-7020U laptops come in two varieties, the one with a 1TB HDD and the other without. While both have the same price tag, the latter is more powerful and capable of handling more demanding tasks. The former has a backlit keyboard and comes with a 4GB memory. The latter offers more power than the former due to its larger screen size, which spans 15 inches.

This is a great daily computing platform, and it has a 256GB SSD and a huge 1TB HDD. The X509 has both a DVD drive and a hard drive, so you get the best of both worlds.
